• [X] No limitation for value: store any JSON-compatable structure.
• [X] Nested set / del value.

Because diesel depends on the libpq for the PostgreSQL backend, you’ll need to install the libpq with vcpkg and vcpkg_cli.

1. Install vcpkg and libpq and vcpkg_cli

# install vcpkg ...
vcpkg install libpq:x64-windows
cargo install vcpkg_cli

1. set environment variable and set toolchain

set VCPKGRS_DYNAMIC=1
set VCPKG_ROOT=your\vcpkgrepo\root
rustup toolchain install stable-msvc
rustup default stable-msvc

1. probe libpq

vcpkg_cli probe libpq
